In the docstring of `define-minor-mode':
[...]
:variable PLACE [...]
PLACE can also be of the form (GET . SET), where GET is
an expression that returns the current state, and SET
is a function that takes one argument, the new state,
and sets it.
I don't understand the meaning of GET. The docstring says it returns
the current state, but where will it return?
